摘　　要：大型水利工程中钢筋混凝土扭坡结构施工成为施工重点和难点,运用扭坡特性建立专用扭坡组合钢模板设计方法,总结渐变扭坡组合钢模板的施工工艺及其支撑技术,能够有效地解决倒虹吸渐变扭坡混凝土成型达到理论设计扭曲面的难题,从而通过改进扭坡结构施工成型质量减小倒虹吸渐变段对整体水能的损失。This paper analyzes how to make the torsional slope concrete an idealized one in the inverted siphon project. It establishes the method of designing torsional slope formwork based on the property of anamorphosis torsional slope and its strut technology,it also solved the concrete confection of inverted siphon anamorphosis torsional slope and decreased the loss of integral water power caused by the poor quality of torsional slope, confection construction.
